OpenAI and AWS Expand Partnership to Bring GPT-5.5, Codex, and Managed Agents to Amazon Bedrock
OpenAI and Amazon Web Services (AWS) have enhanced their strategic alliance, enabling the availability of OpenAI models, including the advanced GPT-5.5, on Amazon Bedrock. This collaboration, revealed on April 23, 2026, also introduces Codex, OpenAI's coding assistant utilized by over 4 million users weekly, to AWS through Bedrock. Furthermore, Amazon Bedrock Managed Agents, powered by OpenAI, are now in limited preview, allowing businesses to implement sophisticated agents in their AWS settings. These features facilitate the use of OpenAI in application development, software engineering, and agentic workflows while benefiting from AWS's robust infrastructure and compliance measures. Codex can be accessed via the Bedrock API, Codex CLI, desktop application, and Visual Studio Code extension. All customer data is handled by Amazon Bedrock, and eligible clients can count Codex usage towards AWS cloud commitments. The partnership seeks to streamline the journey from experimentation to production for enterprises leveraging AI at scale.
